| # o catch load command does not stop for implicit loads. |

| # o info line non-existent-function dumps core |
| # o clear non-existent function dumps core |

| # |
| # o gdb prints static and extern variables in shlibs incorrectly. |

| # |
| # o deferred breakpoints should kick in for shlibs loaded explicitly |
| # with the sharedlibrary command. |
| # o GDB confuses export stubs with actual function. |
